High CPU Temperature Causing PC to Slow Down

10-01-18, 20:47

Hi,

I noticed my computer running slow for past few days, i was getting low fps, i thought it was my GPU. But i checked the temp today using http://openhardwaremonitor.org/ and in my bios my CPU is showing as 97-99 `C consistently.

Ive noticed my closed water cooling system has been making a lot of noise recently as if im doing something which is very CPU intensive. I checked my CPU usage in task manager and its usual idling speeds 5/6 %

This high CPU temp is most likely the cause of my slow computer?, How can resolve this issue? is it caused by my fan?

Remove the block, wipe it clean (use isopropenyl for better results but something like a wet wipe works fine), apply some new thermal paste, secure the block in position again and ensure the radiators aren't clogged with dust. If temps don't improve, it might be time to replace it.

In regards to your CPU fan 1 issue, your motherboard might only have 1 header for CPU fans (PWM fans that spin faster as temperatures increase) and its a red herring from the software or you have your cooler pump connected to the one of the headers, if your motherboard has 2 CPU headers.

My motherboard is a MSI 97A MS 7916, i can see that there are 2 ports plugging into something labelled CPUFAN1 and CPUFAN2 on my motherboard. I assume this is correct, aria built my computer, so im confused why the command center is not showing any RPM for CPUFAN1. Is this an issue which could be causing high temps?

In the below image you can see in the top right CPUFAN1 and CPUFAN2 both are connected by what appears to be my cooler wires.

Theres a backplate that the holes line up with, all you should need to do is gently push one of the screws into place and turn the screw a few times so its secure (not tight) before moving on to the one in the opposite corner. once they are all in place, tighten them up fully and you're good to go.

Line all 4 screws in to position without tightening them, that'll tell you if its the inside or outside hole on the moun that should be used. It should have instructions that will tell you which hole fits which socket.

Backplate, there should be something else under this block, or do you mean the screws mounted onto the motherboard?
